Smart Carbon Monoxide and Smoke Safety Alarm with LCD Display and 85 Decibel Sound

Carbon monoxide is a silent threat, as it is colorless and odorless, making it undetectable until it’s too late. Ensure peace of mind in your home, office, dormitory, or anywhere you need reliable safety coverage.

Equipped with an advanced electrochemical sensor, this device continuously monitors carbon monoxide levels, providing real-time readings. When CO levels increase, the LED light blinks, the LCD displays the current measurement, and the alarm is triggered. The smoke detection feature works simultaneously, so both dangers activate the same alarm system.

Powered by batteries, this alarm functions seamlessly during power outages, eliminating the need for complicated wiring or electrical installation. The batteries are designed to last for up to 36 months, reducing the hassle of frequent replacements. It comes with screws that make mounting easy on any wall or ceiling within minutes.

The LCD screen notifies you of low battery levels and any malfunction, ensuring the device is always operational. It also features a memory function that retains records of past high CO levels and includes a self-test button for regular system checks. Its compact size allows for easy relocation between rooms, dorms, or travel without the need for reinstallation.

  • ELECTROCHEMICAL CO SENSOR: Monitors carbon monoxide levels in real time, activating the alert system when necessary.

  • 85 DECIBEL ALARM: Powerful enough to pierce through ambient sounds and awaken you in case of a CO emergency.

  • LCD CO DISPLAY: Provides immediate visibility of carbon monoxide levels for quick reference.

  • FLASHING LED ALERT: A red light blinks in conjunction with the alarm as CO levels rise.

  • SMOKE DETECTION FUNCTION: Detects smoke simultaneously with CO for comprehensive safety alerts.

  • 36 MONTH BATTERY LIFE: Operates on three AA batteries, lasting up to three years before needing a change.

  • SELF TEST BUTTON: Lets you verify the functionality of the alarm, sensor, and display at your convenience.

  • HIGH CO MEMORY: Keeps a log of previous dangerous carbon monoxide readings for your review.

Before you order

Delivery How long will this take to arrive?

Most orders arrive within 4–12 business days of being placed. That covers 1–2 business days to prepare and dispatch your order, then 3–10 business days in transit depending on where you are. These are estimates based on what our carriers normally achieve, not guarantees. A tracking link is emailed the moment your parcel leaves us.

Returns What if it isn't right for me?

You have 30 days from delivery to start a return, for any reason. Email us first and we'll send the return address within 24 hours on business days, then ship the item back within 14 days. Items need to be unused and in their original packaging wherever that is still possible. Return postage is paid by the customer — unless the item arrived damaged, defective or incorrect, in which case we cover it.

Read the return policy
Refunds When does the money come back?

Once your return reaches us and passes inspection, we confirm by email and refund the original payment method within 5–7 business days. Depending on your bank or card provider, it can take a further 5–10 business days to appear in your account.

Read the refund policy
Tracking Where is my order right now?

Every order ships tracked. Use the link in your dispatch email, or enter your order number on our tracking page at any time. Carriers usually need 1–3 business days to register the first scan, so an empty page straight after dispatch is normal.
